Best Refillable Candle Systems UK (2025 Guide)
Refillable candle systems are becoming more popular in the UK. Read on to find out why more customers are choosing to switch to sustainable, reusable home fragrance.
Refillable candles have moved from a niche concept to a mainstream expectation. People are tired of throwing away jars, tired of messy clean up and tired of paying full price every time a candle burns out. In 2025, the market has started to split. Some brands offer quick, affordable refills. Others focus on handmade pots and artisan design. And then a few aim to reinvent the refill system entirely.
Below is a simple breakdown of the most talked about refillable candle options in the UK, including the strengths, the weaknesses and what customers should consider before choosing a system.
1. Casa di Ovia
Best for people who want a luxury refillable system that is clean, engineered and effortless.
Casa di Ovia has redesigned the refill process from the ground up. Instead of traditional wax blocks or re pour refills, the brand created a crushable aluminium insert that drops straight into a sculptural vessel. When the candle is finished, the insert crushes easily for recycling and the vessel stays completely clean.
What makes it stand out
• Sculptural vessel designed as a permanent home decor piece
• Matte aluminium refill inserts with 317 g of coconut and soy wax
• No scraping, boiling or cleaning needed
• Consistent fit and burn quality every time
• Four refined scents made for modern interiors
• Subscription option with free UK delivery
Price
Starter Kit £70. Refills £30 to £35.
Why choose Casa di Ovia
It is the only system in the UK that combines design, engineering and sustainability in one product. You do not reuse the vessel. You replace the insert. The result is clean burning, zero mess and a truly elevated ritual.
2. Pott Candles
Best for people who love artisan ceramics and handcrafted homeware.
Pott Candles built their brand around handmade ceramic vessels. Each pot is unique and the aesthetic appeals to customers who enjoy artisanal, rustic design.
